The iPhone "..." could not be synced because the sync session failed to start

I am having this problem too and None of these posts mean anything to me.....

I have Os 5.1 on the iphone and Itunes 10.5.3.3

Please help!

Lyssia, restore the phone from backup.

same here. restoring from backup didn't work.

Transfer purchases doesn't start the sync either.

iPad syncs fine.

If you have iTunes Match enabled in your music settings, disable it, and then restore from backup again...

it's disabled. However, iPad syncs fine with match on. (iPad is a clone backup of iPhone 4S)

somethings that may be of use:

Under My Computer, iPhone shows up, but the picture thumbnail is not an iPhone but what it seems to be a camera with the name Apple iPhone.

Also, autoplay doesn't work either.

This should work... Follow these steps exactly for uninstalling and reinstalling iTunes http://support.apple.com/kb/ht1925

if i uninstall and reinstall itunes wouldn't the apps be removed from my iDevices as well?

also, the phone doesn't sync in other computers either. I think what you're suggesting is not going to help at all.

Nothing from your library will be removed at all after uninstalling. All the paths to you library including apps, songs, videos, etc will be tied to your user ID that you use to sign in iTunes. Your phone wouldn't sync on other computers anyway unless you have authorized it to do so (you're allowed up to 5 computers)

try restarting your com, it worked for me

lol no nexasx restarting the computer doesn't work. 🙂

@booldude: my friend, my pc is not syncing, my laptop is not syncing, my work pc is not syncing. all 3 pcs are authorised.

all errors are the same. the sync failed to start.

my iPhone is showing as a digital camera. drivers are from 2006 ⚠.. so... trying to find a way to update them

it's a 4s

In that link I gave you, there are multiple software drivers you are installing and reinstalling in addition to iTunes. You have to do it in the order it gives you, and hopefully it will work...

Fixed my phone. My back up was corrupted during install of ios5. Progressively got worse over the months. Only thing that worked was restoring my phone and backing up to my bf's back up. Then I was able to sync my apps and music but everything else I had to rebuild from scratch :s

do you have any links for mobile device drivers for iPhone 4s? I'm getting close in finding the issue.

my computer system recognises my iphone 4s as an MTP-USB device

I'm sorry, I do not... However, I would think the 4 and the 4S would have the same drivers, although I could be wrong....
